• TRDIORC
TRDIORC selects whether GRC or GRD is used as an output compare register or an input
capture register. When an output compare register is selected, the output setting is selected.
When an input capture register is selected, an input edge of an input capture signal is selected.
TRDIORC also selects the function of the FTIOA to FTIOD pins.

When IOD3 = 0,
00: No output at compare match
01: 0 output to the FTIOB pin at GRD compare match
10: 1 output to the FTIOB pin at GRD compare match
11: Output toggles to the FTIOB pin at GRD compare
match
When IOD3 = 1 and IOD2 = 0,
00: No output at compare match
01: 0 output to the FTIOD pin at GRD compare match
10: 1 output to the FTIOD pin at GRD compare match
11: Output toggles to the FTIOD pin at GRD compare
match
When IOD3 = 1 and IOD2 = 1,
00: Input capture to GRD at rising edge at the FTIOD
pin
01: Input capture to GRD at falling edge at the FTIOD
pin
1X: Input capture to GRD at rising and falling edges at
the FTIOD pin
